Data cards aren't yet available in the new markets, but tethering on a phone is available. As usual, all plans include unlimited everything-except-data; data speeds are throttled past 2GB, 5GB or 10GB, depending on whether you get the $50, $60 or $70 plans, and tethering is allowed on $60 and $70 options.
